Hi
i am using the following way to dissallow ssh connects without having the Problem of specific IPs or something else.
Before you get access to the machine you must visit a webpage protected by httpauth. This start a small script that put the Remote Adress into a list. Only if your ip is on the list and not older than 5 min. you gain access via ssh.
For this i used only iptables the Skript and apache. The only Problem is when the httpd hangs on.
If you want more Information write me.
